Problems solved by technology

[0002] In the process of recording data on a recordable optical disc (such as: CD-R), a servo error (Servo Fail) caused by an external shock (Shock), or a recording error (Writing Fail) caused by a power cut, etc., When data logging is aborted abnormally, such as figure 1 As shown, when an unnecessary unrecorded interval (B-C) occurs, especially when a record-once disc (CD-R) is used, the data recording method that forms a pit (Pit) on the recording surface of the disc is used, so it is terminated abnormally. When data is recorded, the place where the data was last recorded cannot be accessed, so not only all the data recorded in the past is lost, but also data cannot be recorded in the above-mentioned unrecorded period, and as a result, there is a problem that the disc cannot be used at all.

Abstract

A CD recording method especially refers to a data record method when the data record on CD is urgently interrupted due to switch cut-off including: When a CD with data record interrupted unusually requests for record, a light pick device is moved to the beginning position of a program zone on CD to move on a certain trace to test the carved signals on the moving present position, and if data are recorded or not from the generated signals. If the present position is judged to be unrecorded zone, the data record operation begins to form after the said moved present position.

Description

(1) Technical field [0001] The present invention relates to a data recording method of an optical disc, in particular to a data recording method of an optical disc whose data recording is abnormally suspended due to reasons such as power off (Off). (2) Background technology [0002] In the process of recording data on a recordable optical disc (such as: CD-R), a servo error (Servo Fail) caused by an external shock (Shock), or a recording error (Writing Fail) caused by a power cut, etc., When data logging is aborted abnormally, such as figure 1 As shown, when an unnecessary unrecorded interval (B-C) occurs, especially when a record-once disc (CD-R) is used, the data recording method that forms a pit (Pit) on the recording surface of the disc is used, so it is terminated abnormally. When data is recorded, the place where the data was last recorded cannot be accessed, so not only all the data recorded in the past is lost, but also data cannot be recorded in the above-mentioned...
